Susceptibility Testing for Staphylococci Other Than S. Aureus

Explore the complexities of susceptibility testing for staphylococci other than S. aureus (SOSA) in this 40-minute video from the American Society for Microbiology. Delve into the challenges posed by MALDI-TOF identification and the intricacies of detecting methicillin resistance across different species. Learn about changing breakpoints, testing methods, and the rationale behind the shift from "coagulase-negative staphylococci" to SOSA terminology. Join experts Dr. Romney Humphries and Dr. Lars Westblade as they discuss the gold standard for methicillin resistance detection, upcoming changes in breakpoints, and the implications for clinical microbiology laboratories. Gain insights into mechanisms of resistance, the significance of MIC levels, and the role of penicillin-binding protein 2a. Access additional resources, including related studies and a micro-comic strip, to enhance your understanding of this evolving field in microbiology.
